Abstract: A method may include receiving, at a serving call session control function (S-CSCF) device, from a home subscriber server (HSS), a subscriber profile that includes a first subscription state associated with a user device. The first subscription state is one of a plurality of subscription states in addition to barred and not barred. The method includes routing messages to at least one of a plurality of application server devices based on at least one initial filter criteria (iFC) associated with the first subscription state. The method also includes receiving, at the S-CSCF device and from the HSS, a subscription state change to a second subscription state from the HSS, wherein the second subscription state is one of the plurality of subscription states. The method further includes identifying at least one iFC associated with the second subscription state, and routing messages to at least one of the plurality of application servers based on the at least one iFC associated with the second subscription state.

Abstract: A device may receive a first request to authenticate a user device for an emergency phone call requested by the user device via a wireless local area network (WLAN). The device may authenticate the user device based on the first request. The device may provide an authentication acceptance message, indicating that the user device is authenticated, based on authenticating the user device. The device may receive a second request, based on providing the authentication message, to establish the emergency phone call. The second request may include an emergency access point name (APN). The device may determine that the emergency APN is not provisioned for the user device. The device may provide, based on determining that the emergency APN is not provisioned, an instruction to allow the emergency phone call from the user device using the preconfigured APN.

Abstract translation: 设备可以经由无线局域网（WLAN）接收用于用户设备请求的紧急电话呼叫的用户设备的第一请求。 设备可以基于第一请求认证用户设备。 设备可以基于认证用户设备来提供指示用户设备被认证的认证接受消息。 设备可以基于提供认证消息来接收第二请求，以建立紧急电话呼叫。 第二请求可以包括紧急接入点名称（APN）。 设备可以确定不为用户设备提供紧急APN。 该设备可以基于确定不提供紧急APN来提供允许来自用户设备的紧急电话呼叫使用预配置APN的指令。
